The Parachute and Cables (sometimes seen as "Parachute Assisted Cables") system seemed like one of those desperate measures a country under nightly air attacks would reach out for. It did indeed work though. One of my 101 Squadron subjects did this upon enlistment (later became a F/Engineer).

There is some general information here_:

I was also sent a six page article "Clipping the Eagle's Wings" on the PAC system (and other equally interesting apparatuses like the balloon mine) from the August 2006 "Aeroplane" magazine (thanks, Joss). If you PM me your mail addy I will send this to you.

I am trying to tie the PAC (Parachutes and Cables) bit in with 78 Wing (Chain Home) .... which was where he was posted at the time. As Chain Home (and 78 Wing) was radar related I am not sure of the connection. Any thoughts?
